“Free will is an illusion: all human actions are predetermined by prior causes.”
This claim asserts that metaphysical determinism eliminates genuine free will, as every decision results from a chain of physical and psychological causes beyond personal control. Neuroscientific experiments, like Libet's, show brain activity precedes conscious choice. Critics argue this ignores quantum indeterminacy or compatibilist definitions of freedom, sparking debate on moral responsibility and justice.

4I think the Libet experiments are pretty compelling. If brain activity happens before we're even aware of choosing, it really suggests our sense of control is just a story we tell ourselves after the fact.
But quantum indeterminacy might introduce genuine randomness, which isn't the same as free will. Even if it's not fully deterministic, that doesn't give us conscious authorship—just unpredictable particles.
If we accept determinism, how do we justify punishing criminals? Do we really want to treat all human behavior as just a product of prior causes, or do we need some concept of choice to make society function?
Compatibilists have a point: free will doesn't need to be metaphysical magic. It's about acting according to your own desires and reasons, even if those desires are caused. That's what matters for responsibility, not some uncaused cause.
